Description
Equipo separador de aceites.Oil separator equipment.
La presente invención se refiere a un equipo que ha sido especialmente concebido para la separación de aceites, como por ejemplo depósitos de emulsión de detergente utilizada para el lavado de piezas, con el objeto de extraer el aceite que aportan tales piezas a la operación de lavado, con la evidente finalidad de mantener la emulsión de detergente en óptimas condiciones.The present invention relates to equipment that It has been specially designed for the separation of oils, such as for example detergent emulsion tanks used for the washing parts, in order to extract the oil they provide such parts to the washing operation, with the obvious purpose of keep the detergent emulsion in optimal conditions.
Así pues, el objeto de la invención es conseguir un ahorro de fluidos solubles y detergentes al efectuar menos cambios de baño, minimización de mano de obra al alargar los periodos de limpieza cíclica de los equipos, y mejoras ecológicas al emitir menor cantidad de residuos a las centrales depuradoras.Thus, the object of the invention is to achieve a saving of soluble fluids and detergents by less bathroom changes, minimization of labor by lengthening periods of cyclic cleaning of equipment, and ecological improvements by emitting less waste to the plants sewage treatment plants
Obviamente el equipo es igualmente aplicable a la separación de aceite en otros procesos industriales, a la separación de taladrina, etc.Obviously the equipment is equally applicable to the oil separation in other industrial processes, to the taladrina separation, etc.
La invención resulta de especial aplicación en el ámbito de la industria automovilística y al de la transformación del acero, así como otros sectores que sufran contaminaciones por aceites y lodos.The invention is of special application in the scope of the automotive industry and the transformation industry of steel, as well as other sectors that suffer contamination by oils and sludge
En cualquiera los ámbitos de aplicación práctica anteriormente citados, tanto en el de mecanizado como el de lavado o desengrasado, se utilizan baños con un producto adecuado, como por ejemplo una solución de detergente, que alojados en un depósito son paulatinamente contaminados por aceites extraños y por partículas finas que se mantienen en suspensión.In any field of practical application previously mentioned, both in machining and washing or degreased, bathrooms with a suitable product are used, as per example a detergent solution, which housed in a tank are gradually contaminated by foreign oils and particles fine that remain in suspension.
Cuando el nivel de contaminación alcanza una cota preestablecida el baño debe ser eliminado y sustituido por otro nuevo, con las consecuentes y negativas repercusiones que ello trae consigo tanto desde el punto de vista económico como desde el punto de vista ecológico.When the level of contamination reaches a level preset the bathroom must be removed and replaced by another again, with the consequent and negative repercussions that this brings I get both economically and from the point of view Ecological view.
Evidentemente la extracción del aceite de dicho depósito supondria un alargamiento de la vida útil del baño, lo que a primera vista parece sencillo dado que, por la diferencia de densidad, el aceite tiende a flotar sobre la superficie del baño de detergente o del tipo de que se trate.Evidently the oil extraction from said deposit would extend the useful life of the bathroom, which at first glance it seems simple given that, because of the difference in density, the oil tends to float on the surface of the bath of detergent or the type in question.
Sin embargo las diferentes soluciones adoptadas al efecto en la práctica, han dado lugar a unos resultados poco satisfactorios, a la vez que, por lo general, se trata de instalaciones voluminosas, costosas y de dificil mantenimiento.However the different solutions adopted to the effect in practice, they have resulted in little results satisfactory, while, generally speaking, it is about bulky, expensive and difficult maintenance facilities.
El equipo que la invención propone ha sido concebido para separar por diferencia de densidades el residuo no miscible con el producto original, es decir los aceites.The equipment proposed by the invention has been designed to separate the residue not by density difference Miscible with the original product, that is, oils.
El equipo cumple además una serie de funciones complementarias, concretamente las siguientes:The equipment also fulfills a series of functions Complementary, specifically the following:
- --
- Detección y corrección de espumas.Detection and correction of foams
- --
- Control de niveles, adición de agua y de producto.Level control, addition of water and product.
- --
- Determinación de valores tales como concentración de pH.Determination of values such as pH concentration
Para ello y de forma más concreta el equipo que la invención propone, destinado a actuar sobre el depósito contenedor del baño de que se trate, consiste en una bomba que actúa sobre la parte superior de dicho depósito, es decir sobre la zona próxima al nivel del fluido en el interior del mismo, en la que se acumulan los aceites residuales, bomba que aporta el producto absorbido a otro depósito en el que se lleva a cabo el tratamiento del mismo.To do this and more specifically the team that The invention proposes, intended to act on the deposit container of the bath in question, consists of a pump that acts on the top of said deposit, that is on the area close to the level of the fluid inside it, in which residual oils accumulate, pump that brings the product absorbed to another deposit in which the treatment is carried out of the same.
En este depósito se establecen preferentemente tres compartimentos, si bien dependiendo de los fluidos a tratar puede ser distinto si número y disposición, lateralmente adyacentes, uno sobre el que descarga la citada bomba, en el que se produce una decantación de las partículas de suspensión y desde el que el líquido ya limpio retorna al depósito del baño, a través de una eletroválvula, cuando ésta se lo permite. En dicha fase de decantación las partículas se depositan en el fondo del compartimento, que a modo de tolva las concentra en un punto de cota mínima en el que se establece una válvula manual o automática de descarga o de drenaje, mientras que los aceites se sitúan por flotación en el nivel más alto de compartimento, desde el que rebosan hacia un segundo compartimento, cuando la citada electroválvula se encuentra cerrada.In this deposit they are preferably established three compartments, although depending on the fluids to be treated it can be different if number and arrangement, laterally adjacent, one on which the said pump is discharged, in which produces a decantation of the suspension particles and from the that the already clean liquid returns to the bath tank, through a solenoid valve, when it allows it. In said phase of decantation the particles are deposited at the bottom of the compartment, which as a hopper concentrates them at a point of minimum level at which a manual or automatic valve is established discharge or drainage, while oils are placed by flotation at the highest level of compartment, from which overflow into a second compartment, when the aforementioned solenoid valve is closed.
En el segundo compartimento se produce una segunda fase de decantación, siendo igualmente las partículas extraíbles del mismo por una válvula manual o automática de descarga existente en su fondo, y estando este compartimento asistido igualmente por una electroválvula de retorno al depósito principal, pero con la particularidad de que esta electroválvula actúa en función de la resistividad eléctrica del baño existente en cada momento en el citado compartimento y detectada por una pareja de electrodos, que envían información a un autómata que, debidamente programado, controla el funcionamiento de las electroválvulas, autómata una de cuyas ventajas es que hace el proceso más rápido y eficaz al autorregular el ciclo de separación en base a la concentración de aceites.In the second compartment there is a second phase of decantation, the particles being also removable by a manual or automatic valve existing download in your background, and this compartment being also assisted by a return solenoid valve to the tank main, but with the particularity that this solenoid valve acts according to the electrical resistivity of the existing bath in every moment in the aforementioned compartment and detected by a couple of electrodes, which send information to an automaton that, properly programmed, controls the operation of the solenoid valves, automaton one of whose advantages is that it makes the process faster and effective by self-regulating the separation cycle based on the oil concentration
Cuando esta segunda electroválvula se mantiene cerrada el aceite en flotación rebosa hacia el tercer compartimento, desde el que finalmente es eliminado.When this second solenoid valve is maintained closed floating oil overflows to the third compartment, from which it is finally removed.
Con el equipo de la invención y para un depósito contenedor del baño con una capacidad de 3.000 litros, en el que convencionalmente era necesario efectuar un vaciado semanal, se consigue alargar dicho ciclo operativo, o sea las maniobras de vaciado, hasta al menos los 3 meses, es decir que el rendimiento del baño es del orden de 12 veces superior.With the equipment of the invention and for a deposit bathroom container with a capacity of 3,000 liters, in which conventionally it was necessary to carry out a weekly emptying, manages to extend said operating cycle, that is, the maneuvers of emptying, up to at least 3 months, that is to say that the yield of the bathroom is of the order of 12 times higher.
El equipo está diseñado para poder ser incorporado de forma sencilla a la propia instalación de cada cliente, no interfiriendo en la operación ni en las instalaciones, es de reducido tamaño y forma parte del propio depósito, aprovechando el mismo, con las consecuentes ventajas que de ello se derivan.The equipment is designed to be easily incorporated into the installation of each customer, not interfering with the operation or facilities, It is small in size and is part of the deposit itself, taking advantage of it, with the consequent advantages that drift
Como ya se ha dicho con anterioridad, dependiendo de los fluidos a separar los compartimentos serán diferentes tanto en número como en disposición, para facilitar en un momento determinado y por un tiempo la "velocidad igual a cero", que es la que determina y permite una buena decantación y con ello una buena separación.As previously stated, depending of the fluids to separate the compartments will be different both in number as in disposition, to facilitate in a moment determined and for a while the "speed equal to zero", which it is the one that determines and allows a good decantation and with it a Good separation
También en base a las condiciones de los fluidos a separar, se regula el tiempo de estancia de tales fluidos en los diferentes depósitos, es decir que según el programa concebido se regulan desde al autómata programable las diferentes funciones, y se hace de forma que en sí mismo el autómata se autorregule dependiendo de la cantidad de fluido a separar.Also based on fluid conditions to separate, the residence time of such fluids in the different deposits, that is to say that according to the program conceived regulate the different functions from the programmable controller, and it is done so that the automaton itself regulates itself depending on the amount of fluid to be separated.
El equipo incorpora un circuito eléctrico en el que se ha desarrollado una tarjeta de distribución de alimentación que regula y garantiza el funcionamiento de dicho equipo, sin necesidad de sondas o electrodos especiales, consecuentemente sin necesidad de efectuar la limpieza periódica de los mismos.The equipment incorporates an electrical circuit in the that a power distribution card has been developed that regulates and guarantees the operation of said equipment, without need for special probes or electrodes, consequently without need to periodically clean them.
El autómata, con entradas analógicas, ampliables según necesidades, está capacitado para la detección y corrección de espumas, activando una bomba dosificadora que adiciona la cantidad apropiada de liquido antiespumante, está capacitada también para controlar el nivel en el depósito de proceso, por señales activadoras de entrada de agua y de concentrado, y fmalmente está también capacitado para determinación y corrección de parámetros tales como la concentración y el pH; concretamente por comparación y con lecturas programadas en un tiempo a determinar, se actúa para equilibrar las variaciones del pH y condensación, activando válvulas, bombas u otros elementos que permitan el paso de agua, adición de correctores o adición de concentrado.The automaton, with analog inputs, expandable according to needs, is trained for detection and correction of foams, activating a dosing pump that adds the appropriate amount of antifoam liquid, is trained also to control the level in the process warehouse, by water and concentrate input activating signals, and he is also finally qualified for determination and correction of parameters such as concentration and pH; specifically by comparison and with scheduled readings at a time to determine, it acts to balance the pH variations and condensation, activating valves, pumps or other elements that allow the passage of water, addition of correctors or addition of concentrated.

La figura 1.- Muestra, según una representación esquemática, un depósito para un baño de un producto utilizable en el mecanizado o desengrasado de piezas, provisto del equipo separador de aceite que constituye el objeto de la presente invención.Figure 1.- Shows, according to a representation schematic, a tank for a bath of a product usable in the machining or degreasing of parts, provided with the equipment oil separator constituting the object of the present invention.
La figura 2.- Muestra una vista en alzado lateral del depósito decantador/separador que participa en dicho equipo.Figure 2.- Shows a side elevation view of the decanter / separator tank participating in said team.
La figura 3.- Muestra un perfil del conjunto representado en la figura 2.Figure 3.- Shows a profile of the set represented in figure 2.
La figura 4.- Muestra, finalmente, una vista en planta del mismo depósito de las figuras 2 y 3.Figure 4.- Shows, finally, a view in plant of the same warehouse of figures 2 and 3.
A la vista de las figuras reseñadas y especialmente de la figura 1, puede observarse como el equipo que la invención propone está destinado a ser aplicado a un depósito (1) convencional, de los utilizados por ejemplo en el mecanizado o en el desengrasado de piezas, como por ejemplo una emulsión detergente (2), estableciéndose convencionalmente y en el uso de dicho equipo una capa superior (3) de aceites residuales, que se mantienen a este nivel por su menor densidad que la solución o baño propiamente dicho (2).In view of the figures outlined and especially from figure 1, it can be seen as the equipment that The proposed invention is intended to be applied to a tank (1) conventional, of those used for example in machining or in the degreasing of parts, such as an emulsion detergent (2), establishing itself conventionally and in the use of said equipment a top layer (3) of residual oils, which maintain at this level due to its lower density than the solution or bath proper (2).
Pues bien, de acuerdo con la invención, en el equipo participa una bomba (4), cuya boquilla aspiradora (5) se sitúa a nivel de la capa de aceite residual (3) en el interior del depósito (1), bomba (4) que mediante una conducción (6) suministra dicho fluido, por ejemplo con un caudal comprendido entre 15 y 20 litros por minuto, a un depósito auxiliar (7), concretamente a un primer compartimento (8) del mismo, en el que se establece un fondo (9) a modo de tolva que converge hacia una válvula manual de descarga (10), para la eliminación de los lodos o partículas sólidas que por decantación se concentran en esta zona inferior del depósito (8), el cual incorpora además una salida lateral (11) con una electroválvula (12), para retomo al interior del depósito (1) del baño, a través de la conducción (13) mostrada en la figura 1.Well, according to the invention, in the team participates a pump (4), whose vacuum nozzle (5) is locates at the level of the residual oil layer (3) inside the tank (1), pump (4) which, by means of a conduit (6), supplies said fluid, for example with a flow rate between 15 and 20 liters per minute, to an auxiliary tank (7), specifically to a first compartment (8) thereof, in which a fund is established (9) as a hopper that converges towards a manual valve discharge (10), for the removal of sludge or particles solids that by decantation are concentrated in this lower area of the tank (8), which also incorporates a side outlet (11) with a solenoid valve (12), to return inside the tank (1) of the bathroom, through the conduit (13) shown in the figure one.
Un autómata programable establecido en un armario (14) anexo al depósito (7) controla la electroválvula (1), de acuerdo con un programa preestablecido, de manera que cuando dicha electroválvula (12) se encuentra abierta el depósito (8) descarga hacia el depósito principal (1), mientras que cuando se encuentra cenada rebosa hacia un segundo compartimento (15), similar al primer compartimento (8), es decir con un fondo (16) a modo de tolva para concentración de los sólidos de decantación hacia una válvula manual de descarga (17), y con una salida lateral (18) provista de una electroválvula (19), que conecta también con la conducción (13) de retomo al depósito principal (1).A programmable automaton set in a closet (14) attached to the tank (7) controls the solenoid valve (1), of agreement with a preset program, so that when said solenoid valve (12) tank is open (8) discharge towards the main warehouse (1), while when it is dinner overflows into a second compartment (15), similar to first compartment (8), that is to say with a bottom (16) as a hopper for concentration of settling solids towards a valve download manual (17), and with a side outlet (18) provided with a solenoid valve (19), which also connects to the conduit (13) of return to the main deposit (1).
En este caso la electroválvula (19) está controlada por el autómata alojado en el armario (14) a través de las señales de resistividad eléctrica del líquido contenido en dicho compartimento (15) captadas por una pareja de electrodos (20), ya que evidentemente la resistividad del fluido alojado en dicha cámara, como la de cualquier fluido, será acorde con la composición del mismo y consecuentemente distinta en función del porcentaje de aceite en suspensión en el baño.In this case the solenoid valve (19) is controlled by the automaton housed in the cabinet (14) through the electrical resistivity signals of the liquid contained in said compartment (15) picked up by a pair of electrodes (20), since evidently the resistivity of the fluid lodged in said chamber, like that of any fluid, will be consistent with the composition of the same and consequently different depending on the percentage of oil in suspension in the bath.
Cuando la válvula (19) esté cenada los aceites en flotación en este segundo compartimento (15) rebosan hacia un tercer compartimento (21) desde el que salen, también por rebose superior y como se observa en la figura 1, hacia un colector de residuos (22) de capacidad apropiada.When the valve (19) is eaten the oils in flotation in this second compartment (15) overflows towards a third compartment (21) from which they leave, also by overflow top and as seen in figure 1, towards a collector of waste (22) of appropriate capacity.
De esta manera se consigue mantener el baño (2) alojado en el depósito (1) en óptimas condiciones durante un periodo de tiempo considerablemente más largo, del orden de 12 veces mayor de lo que es convencional, como anteriormente se ha dicho.This way you can keep the bathroom (2) housed in the tank (1) in optimal conditions during a considerably longer period of time, on the order of 12 times greater than what is conventional, as previously saying.
